Device, its various ingredients start modularity, and industry reaches its maturity.
Along with the progress of technology, the maturation of industry, unmanned vehicle starts to be applied to increasing technical field,
Demand of especially taking photo by plane has been mature on the whole.Although the technology that employing unmanned vehicle enforcement is taken photo by plane and market are
Start maturation, but be first substantially noiseless mute in the content obtained of taking photo by plane.Use sound collector or wireless wheat
Gram wind carries out the technology the most difficulty of live sound collection, but problematically, the most ripe many rotary wind types
Unmanned vehicle, in operation of taking photo by plane, due to the high speed rotating of rotor, creates the strongest noise, not only makes
Directly collection sound can not realize, and also creates the strongest low-frequency disturbance, and some unmanned vehicles not even collection sound
Sound, only gathers image or broadcasts.
Such as, the patent application of publication number CN201610036966.X discloses a kind of goods and materials of input earthward
Unmanned vehicle, with broadcast platform on unmanned vehicle, for receiving the signal of the mike from ground,
Sound is sent by broadcast platform orientation.And publication number CN201520753935.7 patent application also discloses
A kind of broadcast system being mounted on unmanned vehicle, these applications are all put utilizing unmanned vehicle to carry out sound
The scheme gone out is inquired into, but is all not concerned with how carrying out sound collection with unmanned vehicle.
The most such as Application No. 201520884384.8 patent application document, it is proposed that a kind of can two-way communication
Unmanned vehicle, video camera and sound collector are directly installed on unmanned vehicle body side, not by it
The audio frequency collected is processed further so that the audio frequency collected contains the strongest noise, substantially hardly results in
Preferably communication effect.
It is true that prior art is mainly being paid close attention to, the sound how got for this direct collection carries out noise reduction
Process, thus restore the primary sound effect that can accept, the such as patent of Application No. 201510663629.9
Application documents, just propose a kind of method that sound in taking photo by plane is carried out noise reduction process.But this method is led
Cause to add enormous pressure to the data processing work of unmanned vehicle, and this method problematically, its
Actual effect is the most bad, and the rotor noise of up to 70-80 decibel is bound to primary sound causes the loss being difficult to recover.

Voice synthetic module in processor, or be wirelessly sent to earth station and process, it is synthesized to regard by audio sync
In the middle of frequency, directly obtain high-quality audio frequency and video, without carrying out later stage process again, save manpower and materials.
In the embodiment of the present invention preferably, described task terminates to regain wireless sound collector and remotely pilotless aircraft returns
Returning step, because sound collector is wireless sound collector, wireless sound collector falls sound from the opening part of accommodating mechanism
After near source, unmanned vehicle cannot automatically retract wireless sound collector, it is therefore desirable to user is to pick-up point
Manually regain, and remotely pilotless aircraft returns.
The embodiment of the invention discloses a kind of unmanned vehicle audio collection method, use wireless sound collector as sound
Sound harvester, and clamper and/or ejection mechanism are set in accommodating mechanism, wireless sound collector is projected sound
Near source, the embodiment of the present invention because avoid unmanned vehicle rotor because of high-speed rotary then the noise brought, energy
Enough directly high-quality audio frequency of collection；Should avoid precipitating in crowd overhead during operation the method, in order to avoid injuring pedestrian by a crashing object,
Can first remotely pilotless aircraft low altitude flight to target proximity, the most again by wireless sound collector opening from accommodating mechanism
Hang at Kou, to ensure safety.The embodiment of the present invention is simple to operate, and greatly reduces manpower and time cost,
Improve efficiency of taking photo by plane.
Content during other content sees foregoing invention embodiment in the embodiment of the present invention, does not repeats them here.
The present invention can bring the technique effect that these are useful: unmanned vehicle audio frequency disclosed in the embodiment of the present invention
Acquisition system and audio collection method thereof, by arranging accommodating mechanism, and at accommodating mechanism on unmanned vehicle
The opening that upper setting can freely be closed, separates sound sound collector with unmanned vehicle, and is put by sound sound collector
Put near sound source, the noise that unmanned vehicle rotor high speed rotating is brought can be prevented effectively from, improve sound
The audio quality that sound collector directly gathers, thus reduce manpower and time cost, decrease energy consumption, improve
Shooting efficiency.
Obviously, those skilled in the art can carry out various change and modification without deviating from the present invention to the present invention
Spirit and scope.So, if the present invention these amendment and modification belong to the claims in the present invention and etc.
Within the scope of technology, then the present invention is also intended to comprise these change and modification.
